Thanks Angela. I've tried already and what I received was this list of formalities that my company needs to comply/prove to them about their own pension fund, so the NL pension fund can consider to move the money to CH. Problem is that my company is not going to move a finger (and I can't blame them)to provide all this, specially when they just give away the money on their pension when the employee has left.
I suppose it gaves the pension fund a better position if they are managing thousand/million of Eur from plenty of people than if you are constantly giving bits away.
